12 Claims. 1

The present invention is directed to windows and more particularly to such a structure wherein access may be had from the inside of a window to the outside for purpose of cleaning the same.

It is, of course, necessary to periodically clean windows and in windows of the double-hung type, it is extremely difilcult to adequately clean the outside of the windows without special equipment. It is highly desirable that access he had to the outside of all of the panes of glass from the inside, without undue strain on the part of the window washer and without the necessity for using special apparatus. It is possible to have safety hooks on .the outside of the window frame and the window washer to have a safety belt whereby said washer may stand upon the outside of the window ledge and wash the Wil'ldOWs from the outside. However, this is not feasible in the great majority of dwelling places, as it requires considerable skill and there is a grave element of danger involved.

The present invention is intended and adapted to overcome the dimculties of access to the outside of window panes in double-hung windows and to provide a construction wherein from the inside of a building, the outside of said panes may be easily and readily reached for washing.

It is among the objects of the present invention to provide a structure of a window sash wherein at least one of the panes thereof shall be movable in such a manner as to provide an opening through which the hand. of the worker may be inserted for the purpose of cleaning the outside of the window.

It is also among the objects of the present invention to provide a structure wherein one of the panes of a multiple pane window sash ma be made so movable and access to the other panes be obtained through the opening of the movable pane.

It is still further among the objects of the present invention to provide a movable pane structure which will allow the pane to be shifted in position or entirely removed from the panel in which it is mounted.

In practicing the present invention, there is provided any of the usual forms of window sashes which are mounted in a suitable window frame. Such sashes may be made of wood or metal construction or of any other suitable material. In the case where each window sash contains a plurality of window panes each mounted in a separate panel, one of the panes is made movable. It is provided with a frame binding the edges of the glass and a slot is provided in a side member of the sash through which the pane may be moved,

The sides and bottom of the panel in which the movable frame fits is provided with specially designed sprin members which act to hold the pane in position and are also adapted to provide a waterproof joint between the pane and the panel. To facilitate movement of the pane, there is also provided one or more handles in the frame thereof, which handles are normally in a concealed position and which may be utilized to obtain a firm grip on the frame in order to move the pane.

In another aspect of the invention where the window sash contains a single relatively large pane, the same or a different type of structure may be provided. According to a modification of the present invention, the pane is provided with a closely fitting frame and is mounted within the sash. The mounting may include a frame with hinge members which directly unite the frame with the sash so that when it is desired to clean the window, the frame is rotated about the hinge to open the same inwardly. In place of direct hinges, other means may be provided as, for instance, a sliding hinge joint whereby the frame ma be pulled forwardly, whereby a hinge is provided and the frame may then be rotated about the hinge or may be entirely removed from the sash.

Fig. 13 is a fragmentary enlargedcross-sec tional View showing the junction of movable pane and sash of Fig. 9; and

Fig. 14 is an elevational view of a modified form of spring for said sash.

The window frame! is provided with upper and lower sashes 2 and In a central panel of at least one sash is a movable pane fitting into panel formed by cross pieces 6. The other panes 1 are held in position by putty 8 or the like.

Movable pane 4 is provided with a sash frame 9 preferably of thin metal or plastic and of a single piece of material which is bent around and closely fits against the glass. It is bent around the corners so that the thickness of metal at the corners is approximatel the same as the remainder of the frame. Cement may be introduced between the frame 9 and glass 4.

A flat spring lining consisting of leg l0 having an angular leg ID is inserted in the panel and secured thereto by tacks II along leg ii) thereof. The other leg is bent as shown at l2 sub stantially parallel to H1 and has a right angle portion [3 adjacent the bottom of the groove of the panel. As preferably constructed. it does not quite touch the bottom of the panel. A bowed portion I4 is provided and the end thereof is placed a sufficient distance from element i2 to allow limited movement of said end of portion I 4.

In place of a unitary frame 9 there may be provided a two-part frame, as shown in Fig. 3. It consists of an angle member having legs l5 and [6, said member being fitted to one side and the edges of glass 4. A similar angle member having legs I? and I8 is fitted on the opposite side of glass 4 with leg l8 fitting over leg l6.

Various forms of springs may be used, as for example that shown in Fig. 4 is. provided with legs I0 and lfl, the latter being secured to the bottom of the groove of the panel. Leg i2is integral with the body portion l9. In Fig. 5 a modified form of spring is shown wherein there are two members, one of which consists of legs 20 and 2|, with a body portion 22 extending from the latter. A second spring member 23 is secured to member 2!] by rivets 24. It also has a body portion 25. By this structure. a greater amount of springiness is obtained both at the side and at the bottom of the groove.

The top of thepane frame 9 as shown in Figs. 7 and 8 is provided with and a part of a relatively wide edge 26 integral with frame 9 and extending a substantial distance above the top of the pane 4. A pair of slots 28 are provided in member 28 and handles 29 are introduced to cover the same. Slot 2! is provided along the top edge of sash frame 3 above pane 4. Means may be provided 'to prevent accidental removal of handles 29 after they havebeen inserted. Each handle has a pair of depending legs 30 and wings 3| and 32 extending laterally. Normall they rest upon,

the top edge 33 of glass 4 and handle 29 is almost flush with member 25. In use one grasps handles 29, thereby lifting wings 3] and 32 against the inside of member 26 and the pane may be lifted and slid in its groove with the strain being distributed on the frame and thus there is no danger of cracking or breaking the glass.

Provision is made so that not only may the window sash be locked but also the sliding pane held against accidental displacement. For this purpose there is provideda latch 34 pivoted at 35 on the top of sash 3 in a position adjacent to slot 21. A keeper 36 is secured opposite pivot 35 on sash 2. Latch 3% when in the closed position shown in Fig. 6 not only looks the sashes against relative movement, but also looks glass 4 against movement. When latch 34 is opened, it may be opened partially to still overlay glass 4 or fully to allow the glass 4 to be pulled out of place.

In the modification of the invention shown in Figs. 9 to 12, there is'provided a window sash 40 having a single glass or other pane therein. A frame 42 is provided around glass ll. Hinges 43 are provided parallel with the lower edge of and attached to the mounting thereof, whereby pane 4! may be rotated about a horizontal axis. In Fig. file, the pane M is slidable.

The frame and glass are covered by a facing 44 having extending flanges 45 around the edges thereof to cover at least partially the window sash. A hinge may be formed therein, as shown in Fig. 10, said hinge comprising a depending portion 46 on facing 45 in substantial contact with cylindrical portion l! of sash 4c. The facing further has a recessed inner portion 48 complementary to cylinder 41. In this case, when it is desired to open the pane 4|, the assembly is pulled forward until recess 48 contacts cylinder 41, as shown in dotted lines in Fig. 10. Then the frame may be pivoted about such a hinge or it may be'lifted clear of the window sash.

To assist in the handling of the pane, a pair of handles 49 is usually provided on the sides of flange 45 by rivets 50. Also, on the facing are rivets 5! passing through slots 52 in angle mem bers 53 constituting a slidable latch. Keepers 54 extend from sash 40 through. suitable openings in flange 45 and act as the keepers for the latches. Thereby the window pane may be held securely in place when it is in closed position.

In order to provide a weather-tight joint, the face of the sash adjacent to the frame is pro vided with a specially constructed spring mem: ber made of flat material. It consists essentially of a flat portion 55 adapted to contact the edges of the frame of or glass 4i and integral with a parallel portion 56 which contacts with the window sash. An angle 57 at the opposite end of 56 rests in the bottom of the recess or groove of the window sash. It may be held in position by means, not shown. Also to retain the spring in its proper position, it is provided with an angular portion 58 integral with portion 55. A suffioient space 59 remains between parts 56 and 53 to allow of a compressive movement of the spring due to pressure by the glass. 7

Preferably means are provided so that when the glass is in open position, its movement is lid ited. This is accomplished by providing earsfifl and 6| on the facing and sash, respectively. A cord, chain, cable or the like has its ends'held in said ears. When the window is in closed position, the cable is held within the sash and is not visible from the outside. It is of sufficient length so that when the glass 4| is pivoted about its hinges, the correct amount of opening is rovided.

An alternate arrangement to weather-proof the glass ll consists in providing cement, putty or the like 53, whereby frame 42 is sealed on to glass ii. The spring consists of a bottom member as, a bowed portion 65 contacting oneside of the glass and a fiat portion 66 bearing against sash All. In Fig. 14 is shown a still further type of spring capable of use in the present invention. It consists of a member 68 which is angular in cross-section and a co-extensive angular 'mem ber 69 integral therewith. A bowed portion extends from angle 69.

There has been provided in the present inven tion double action fiat spring linings which cover the side and bottom of the grooves of the sash. Thereby the pressure of the movable pane-allows the linings to retract in two directions which gives complete protection against weather. Also, the fiat spring linings have the additional important function of holding the sliding pane in any position in which it may be placed. The flat spring linings also take up vibration and prevent or loosening of the movable pane.

Although the invention has been described setting forth several embodiments thereof, the invention is not limited thereto but many variations in the details may be made within the scope of the invention. For instance, a single solid or laminated pane in a sash may be made sliding instead of pivoted. The frame surrounding the pane is of uniform thickness and may be of a single piece or of any number of parts. The movable window may be utilized as a ventilator or one or both of the window sashes may be equipped with the same. Each has the advantage that the appearance of the movable pane is indistinguishable from the fixed panes.

The spring linings may be made of bronze or any other ferrous or non-ferrous metal which is resistant to weather. The size, thickness and strength of the spring linings vary with the conditions and the particular application. The form of the spring linings may be varied greatly as many forms can be adapted for the particular purpose involved, provided that sufficient space is provided for compression of the spring linings due to the pressure of the glass thereon. The

form and character of the handles 29 may bechanged at will and the wings 3| and '32 may be made foldable against legs 3!] for the purpose of inserting into member 26. The slots for the handles '29 may be partly closed to hold the handles in position after insertion, so as to prevent/hark dles 29 from dropping too far to be conveniently grasped. Any type of cement, putty or the like may be used to seal the glass to its frame. The framed pane may be fitted with springson the inner side of the sash frame, the pane frame fitting snugly against the sash frame. In Fig. 2, member is may be on the weather or outer side of the sash, and putty 8, or equivalent thereofon the inner side of the sash.

These and other variations in the details and construction may be made within the spirit. of the invention and the invention is to be broadly construed and not to be limited except by the character of the claims appended hereto.
